Auto mail confirmation of PO change versions to vendor

Hello all,

Is there a standard way to add a confirmation pop-up message before sending change versions of the PO to the vendor via email? When the user changes the PO and clicks on save button we need to give a pop-up (yes/no) for sending PO in email. If yes send email otherwise no email to be sent to the vendor as sometimes the change is trivial.

Thanks,

Mohamed Ehab
